Application filed December 1G, 1903. Serial No. 184,587. v

To all whom it may concern:

Beit known that EDMUND C. MORGAN, a citizen of the United States, residing at Chicago, inthe county of Cookl and State of. illinois. have invented a new and. usefulv Pick Mining-Machine, of which the following is a specification.

This .invention relates to pick mining machines.

The object of the invention is to provide 'means vfor receiving tl'ierecoil due to the iinpaet of the pick Or other tool.'

A. further Object of the invention is to provide means for relieving the operator of shock or jar due to the impact of the pick or other tool.

A further hbject of the invention is to provide means automatically operated at. the instant of impact of the pick or other tool, whereby the supporting frame is held against recoil or undue shock or jar.

Other Objects Ot the invention will appear niore iully hereinafter.

The invention' consists substantially in the "construction, combination, location and arrangement of parts, all as will be more fully hercinai'te set forth, as' shown in the acconr panying dizziwinos, and nnally pointed out in the appended claims.

Referring tothe accompanying drawings,

and to the various views and reference. signs D appearing 'tliereon,-li`igure l is a view in iop plan` somewhat diagrammatic, showing a. pick mining machine and the application thereto oi a recoil locking mechanism ein` braced within the spirit and scope ot' my in vention. Fig. 2 is a side elevation. Fig. 3 is abroken detail view in top plan, somewhat diagrammatic, showing a inoilified form of automatic locking mechanism 4einbod'yii'ig .the principles of my invention. Fig.' at isla similar view, parts in Section, oitl another modified forni of mechanism embraced within the spirit and scope of my invention.

The saine part .is designatedby the saine re terencel sign wherever it occurs throughout the several views.

'ln the operation of pick mining inachinery itis usually customary to mount the pick or other tool upon a frame or truck having' wheels, by which the Ytraine may be suitably moved into proper position for the pick or other tool to perform its work, the ii'nme being provide-xl with a hand-grip, which is grasped by the attendant in properly positioning the tool for its work. The

I l impact of the pick or other tool against the 'wall vor vein of coal or t-he like 'imparts a x recoil shock or jar to the entire frame and i through the handle or grip which is grasped by the attendant to the arme of the attendant. In rorder to' relieve this shock Or jar upon the attendant as much as possible, and Aalso .in order to relieve the attendant as much as possible of the work, or labor required to properly position and present @the pick or other tool with reifereneeto its work, it has beenl a common practice to mount t-he frame of the machine upon boards or-stringers, which have been tilted at one end so as to be inclined towards the point where the blow of the tool is to be delivered, thereby enabling to carry the same towards the point of apwork. This expedient, however, has not been sufficient to relieve the attendant of in- `iurious shock and jar due to the impact or blow of the pick or tool. and the recoil resu lt ing therefrom.-

p esent invention to provide means 'Or ailimnatically locking the frame carrying the pick or tool and its actuating mechanism at the instant the blow or impact of the pick or tool is delivered, and te automatically ref lease such locking mechanism upon the with drawal movementoi the pic-koi' tool, so as l to leave the saine freeto be shifted or moved by the attendant as occasion may require.

in the accompanying drawings I have merely indicated inv outline and in dotted lines the construction of the pick or tool, its actuating mechanism and supporting framework or truck., and have shown in full lines in the spirit and scope of my. invention.

Referring to the accompanying drawings, reference sign A designates generally the supporting frame of the carriage, which is provided with the gudgeons B, carrying rellers C, upon which the frame is supportec. der D, in which operates la piston E, 'to which is connected the pick or other tool F, a pressure medium being admitted tothe cylinder tor reciprocating the pick or other tool.- or the rod G carrying the same, inv order to enablcthe pick or other tool to perhe of the usual or anv well known constructhe features of improvement embracedwitn.

gravity to operate upon the carriage or V .traine of the machine in a direction tending pliciition of the pick or other tool to its A lt is among the specialpurposes of my The frame A comprises the usual cylinform its desired Objects.'I These parts may.

y,tion and arrangement, and in the specic details thereof form no part of my present-inv' vention.

The carriage in theoperation of the machine and as 4above indicated, ,is

mounted upon the stringers, timbers, boards' or th`e like, H, the latter being anchored to the ground in any convenient manner, as,

for instance,

\ by means of an anchor-bar J, or otherwise.

Incarrying out the principles of my in-v vention I` propose to provide means automatically operated at or immediately before 'the delivery of the blow or impact of the pick or tool yto lock or anchor the carriage or frame carrying the pick or tool vand its actuating mechanism to the ground and ment .of the pick or tool.

againstl recoil, and to automatically release such locking means upon the reverse movej This idea may be embodied in'a wide variety of specific constriictions and arrangements and still fall Within the spirit and scope of my invention.

While, therefore, I have sho-wn and lwill now describevarious constructions and arrangements for accomplishing the desired object,

I do not 'desire to be limited or restricted suitable abutments N on the side or face thereof, or otherwise, as may be convenient.

The other end of the cable or other connection L is hooked or otherwise secured, as at M, to one of the beams or stringers constituting the platformor lsupport therefor, i thereby giving the carriage a ground anchorage. Suitalily connected to each of the drums or pulleys K is one end of a spring O, the other end of each of said springs being connected to its associated stub or gudgeon B, the ytension of said springs being normally 4exerted in a direction to maint-ain the cable or other connection L taut.

In order to lock the machine and its supporting frame `against recoil under the influence of the impact or blow delivered by the pick or tool and at or about the instant such blowor impact is delivered,-I pivotally mount upon the frame adjacent to each drum or pulley K, a pivoted lever P, each having its endv arranged to be rocked into engagement with or between the teeth or lugs N on its associated ldrum' or pulley K. Each lever P is normally held out of engaging relation with respect tothe teeth or ugs N on its associated drum or pulley in anyconvenient manner, as, for instance, by meansv of a spring Q. Associated with each lever P is. a cylinderz-,It-,fin o eratesa piston S, said Ipiston beino suita ly connected to the otherend ofIever P.

From the foregoing description it Iwill-be'y` seen that when a pressure medium is admit# ted .to the cylinders R, the pistons S therein are moved, thereby rocking levers P in a1 direction to carry the free ends thereof into engaging relation with'respectto the teeth or lugs N on'their associated drums or pulleys K, The pressure medium may be of vany desired or suitable arrangement, and

may be controlled in any suitable manner. It is desirable, however,A to so control such pressure medium as to admit the saine to the cylinders R at or immediately before the v delivery of the blow orimpact of the pick or other tool, so that at the moment the pick or other tool delivers its bloT the drums or pulleys K are locked against rotation, and" ally so as to retain the locking engagement of levers P and the drums or pulleys K during the time the blow of the tool or pick is being delivered, and also so as to be automatically released upon the return movement ofthe pick or tool. In Fig. l I have r shown one arrangement for accomplishing this object, wherein a-pipe A communicates with a suitable source of pressure medium, and a pipe B with the exhaust. These pipes deliver into a valve C, normally but yieldingly held in a centered position by spring D to cut o bot-h -the 'supply and ehaust pipes A B from a pipe E. The springs D are arranged on opposite sides of a handle or projection F connected to the valve, said handle or projection arranged, when held in centered or normal position, to extend into the path of a lug G', connected to move or reciprocate with the stem or rod G carrying the pick or other tool F, and the#4 arrangement ot' the valve is such that when v the pick or other tool moves in a direction to deliver its blow or impact the lug G en- Oages the projection or handle F of valve thereby rocking said valve in a direction to open communication between supplypipe A and the service pipe E.

The parts are intended to be so relatively positioned that the 'opening of the supply pipe A and service pipe E to communication with each other is effected at or just before the instant of impact or blow of the pick or tool. Asy the pick or tool continues its movement in a direction to deliver its blow the lug G passes or wipes by valve handle F', thereby permitting said handle to be automatically returnedy or restored toits normaler centered position, thereby cntting v service pipel'] is again temporarily opened pipe E' and exhaust pipe B', and hence per- `that eitlier one orthe other "of these lockings oil" supplyjofthepressure medium to the I service pipeE. 0n the return movement `of the pick or other tool the lug G' engages Jthe valve handle F'f'froin the opposite direction, thereby rocking said valve 'in a direction to open communication between the service mitting the pressure medium which has entered the service pipe E' and the devices presently to be referred to', which are in communi -ationiwith said service pipe to escape to exhaust. Upon the opening of communication between pressure supply pipe A and service pipe yE' the v pressure medium is admitted to each of the cylinders R through the service pipe E', which is arranged to communicate with each of said cylinders, as clearly illustrated. Thus, it will be seen thator just-before the instant of impact or delivery of the blow of the pick or other tool pressure medium is admitted to the cylinders Il, theieby moving the pistons therein and rocking locking levers P into engaging relation with. respect to their associated drums or pulleys K, and hence lockl ing the machine against recoil movement. The pressure medium thus admitted to'the cylinders R is maintained so as to maintain the locking -connection of levers 'It and drums or pulleys K until the return movement of thepick or other tool, when the 'to exhaust. Thus, it will be seen that I provide a mechanism which is automatically locked and released, whereby the shock or jar due to recoil from the delivery ofthe im'- pact or blow of the pick or otherohaistaken up by the cables or other conne lzons L, thereby relieving the operator or attendant. l

It' desired, and in order to still further insure a locking of the frame against recoil movement, I may employ a brake or shoe H', for each of the truck wheels C, each brake or shoe being connected to a piston J', operating in the cylinder K', which cylinders are also in communication with service pipe E', as clearly shown.

If desired, I/may employ a hand-controlled valveL' inl the communication between service pipe E' and the cylinders R and K', so

or braking devices may cut out of operation by hand, if necessary or desirable.

In the operation ofl an apparatus of the. class above referred to it is desirable, to vary or regulate the vertical inclination of the pick or other tool with `reference to the point of delivery of its impact or blow. This may be accomplished by means ofv arod carried by the machine and adjustable relatively theretoand aranged to bear upon the floor of the platform, or upon the planking or other support of the'machine frame. To this end I propose to employ an adjusting rod ranged in communication with service pipe IGZ-so that' at the instant pressure medium is admitted to the lockn'ig and braking cvlvinders it may also be admitted tothe cylinder O', thereby ca using 'plunger N' to clamp tight up against the adjusting rod M', and 75 flience holding said adjusting rod against displacement through shock or jai' due t0 the delivery of the impact or blow of the pick or other tool.

Instead of controlling the supply of operating medium to the locking and brake cvlinders through an independent valve, which isactuated autoinatically by alug on the rod or stem carrying the pick or other tool, it is obvious that the supply and exhaust of'g5 pressure medium may be controlled in many other ways. For instance, I have shown an arrangement in Fig. 4C, wherein the supply of pressure medium to the locking and brake cylinders or to the service pipe E2 may be 90 controlled by the valve A2, which controls the'supply and exhaust of pressure medium to the cylinder for operating the vpick or other tool. It is obvious that the locking of the frame against recoil due to the force of theiinpact or 'blow delivered by the pick or other tool, may be effected mechanically instead of by a pressure medium and still accomplish the desired objects. In Fig. 3 I have indicated an arrangement by which this result.

may be accomplished, wherein the lock-ing lever P2 instead of being actuated pneumatically, as above described, may be .operated by a pivoted leverB2, having a spring arm C2 arraneed to enffafre onearm of lever P2 10 )D b b 7 the other arm of said lever B2 `beingfar'- ranged in the path of a lug G2 on the piston rod G-,so that as .the pic-k or other tool, or the rod G upon which said tool is snpported, advances to deliver its blow the arm 310 of lever B2. is engaged by lug G2, thereby rocking said lever iii a direction for the spring arm C2 thereof to engage one arm of lever P2, the other arm of said lever being arranged to interlock with the teeth or lugs 11'15" -N on drum K.

It is obvious that many modicat'idns2fchanges or variations might be devised foi accomplishing the desired objects, biitfall' embodying the principles of my invention. i2() I do not desire, therefore, to be limited or restricted to the exact details of construction and arrangement shown and above described.

In the use of an automatically releasableI locking mechanism such as above described I am enabled to operate the pick or 'other' tool with less injury or jar to the o` erator' than heretofore, and I am also enaliled to operate the machine on a less inclinel of the' supporting tracks orplanking H, and in fact' 130.

. While l have describedmy invention as applied-toa pick mining machine, it is obvious that the principles thereof are equally applicable to other kinds of machines employing a reciprocating part, and Wherever '1t' may vbe desir-able to lock the machine 25..;against. recoil, shock or jar due to the operation'of the reciprocating part.

It is obvious the releasing of the locking means maybe effected otherwise than -autematically Without ldeparturefrom the spirit and scope of my invention, and, if 'desired, thel construction may be such' asj to.
